This phrase was derived from my English class. We were reading Twain, and David was confused by use of the word 'hither'. He goes, "what, is that like ghetto-speak or something?"
Then this brilliant classmate of ours (me) goes, "fo hither my nizzo". Therefore:
fo hither my nizzo - phrase - used to provoke the anger of a loser who uses old-school speech, as in the word 'hither'.

An extremely redundant little doohickey often used in instant messenger conversation. Why do people say kk? That would be like saying 'okay okay'! Does anyone really say that in real life? (i.e. Hey would you get that video tape 4 me? Okay okay!)
